   Notifications

   Two surfaces. The banner sits above the tab strip, so an active alarm is on
   screen whichever tab is open; the table lives on the Data tab and carries
   the firing counts. Both take their colors from the same --notif-* pair so
   the banner and a count cell agree about what "alert" looks like.
